I'd recommend mounting your chain fall cross beams above and crossing four of the ceiling 2x4 beams. IMHO, what you are doing provides only a fraction of the strength that would be realized if you simply push the insulation out of the way and mount cross beams (like 4x4's) across four of your ceiling beams, and then attach your chainfall to the cross beams (from some apparatus hanging from the top of the cross beams). If you mount something on top of a strong stationary thing (beam), you get the full strength of the beam. Using the hardware I see in the pictures, you are reducing capacity a very significant amount. Terry Farrell On Apr 23, 2010, at 7:24 PM, Noah Frere wrote: > Thanks everyone!
